Power reporting for network power modification

Abstract

Methods, systems, and devices for including power reporting for network power modification are described. That is, a user equipment (UE) and a base station may exchange signaling supporting an MPR update at the UE. In some examples, the UE may transmit, to the base station, a request for resources for performing channel measurements in accordance with a power reduction update associated with the UE. In response, the UE may receive, from the base station, an indication of a set of resources. In some examples, the UE may perform one or more channel measurements using the set of resources based on receiving the indication of the set of resources. In such examples, the UE may transmit, to the base station, a report indicating one or more power parameters associated with the power reduction update based on the one or more channel measurements.
